Absolutely Horrible service

Very horrible service from Nedbank call center... i called in on the 24 july to log a query for a statement i was billed for without be advising of the charge or that there is a charge...the agent said they will log a complaint and they will get back to me before the close of business... i called in everyday there after and no-one can see the complaint or the reps i spoke to... I got called back from a manager and he was going to call me back but that did not happen...I called back to speak to that manager a hour later but the rep cant see what manager i spoke to.. today is the 30th july and as soon as i asked for a manager i was told that they going to place me on hold and get a manager and gues what 29 minutes later I'm still on hold
